This invention relates to wireless communication systems, specifically to optimizing signal strength between two communication devices to ensure reliable communication while minimizing power consumption. The problem addressed is the need to dynamically adjust transmission power levels based on real-time signal conditions to maintain connectivity without excessive energy use. The system includes a communication apparatus with a radio transceiver and a controller. The controller measures the received signal strength from a second device (either an external device or the same apparatus in a different state) when both are in a predetermined communication state.
